Product Description The Sightmark T-3 Magnifier is designed to mount directly behind your red dot or reflex sight to deliver a clean 3x view and absolute co-witness. Its streamlined body is 0.8 inches shorter than the previous model to prevent snagging, while the locking quick-detach flip-to-side mount lets you instantly transition between magnified and unmagnified aiming. Constructed with a rugged aluminum housing and fully multi-coated glass, the T-3 offers bright, sharp images and IP55 water-resistant performance. External windage and elevation adjustments center your reticle, and it is compatible with popular EOTech and Aimpoint systems.
